.SH NAME
std::isgraph(std::locale) \- std::isgraph(std::locale)

.SH Synopsis
   Defined in header <locale>
   template< class CharT >
   bool isgraph( CharT ch, const locale& loc );

   Checks if the given character is classified as a graphic character (i.e. printable,
   excluding space) by the given locale's std::ctype facet.

.SH Parameters

   ch  - character
   loc - locale

.SH Return value

   Returns true if the character is classified as graphic, false otherwise.

.SH Possible implementation

   template<class CharT>
   bool isgraph(CharT ch, const std::locale& loc)
   {
       return std::use_facet<std::ctype<CharT>>(loc).is(std::ctype_base::graph, ch);
   }

.SH Example

   Demonstrates the use of isgraph() with different locales (OS-specific).


// Run this code

 #include <iostream>
 #include <locale>

 int main()
 {
     const wchar_t c = L'\\u2a0c'; // quadruple integral

     std::locale loc1("C");
     std::cout << "isgraph('⨌', C locale) returned "
               << std::boolalpha << std::isgraph(c, loc1) << '\\n';

     std::locale loc2("en_US.UTF-8");
     std::cout << "isgraph('⨌', Unicode locale) returned "
               << std::boolalpha << std::isgraph(c, loc2) << '\\n';
 }

.SH Possible output:

 isgraph('⨌', C locale) returned false
 isgraph('⨌', Unicode locale) returned true
